This directory contains python script to help debugging HPX applications with
gdb. In order to use it, please add the following lines to your ~/.gdbinit:

    source $HPX_SRC_DIR/tools/gdb/hpx.py

    define hook-continue
    hpx thread restore
    end

For a list of commands see `help hpx` inside of gdb.

Notes:

 - The scripts currently only work when HPX is compiled against Boost 1.56
 - The scripts currently only work with the local priority scheduler
 - The scripts currently only work on 64 bit executables
 - The scripts currently only work with the `x86_linux_context` context
   implementation (which is the default on Linux X86_64)
 - The hook-continue is needed because we currently just overwrite the current
   frame with the selected HPX user level context.

By not doing a `hpx thread restore` before gdb continues execution, your
program will abort.
